This post was updated on: 01/06/2017:

This thread is here providing information on our high flowed or built turbos as well as installation and trouble shooting. I'm happy to help or assist with every one who is currently using or looking to purchase our products or services.

Brief Introduction about our selves: We are Australian based turbocharger manufacture in Melbourne, We worked with experienced and skilled local engineers to produce our goods and we've been doing that since Oct 2007. We constantly update our production turbochargers and will do our best deliver value to our customers.

My name is Stao you can PM or contact 0413457185 if any assistance is required.

For our High flowed RB25 Turbos, they comes in 21U or OP6 from factory. The 21U rear housings are smaller can capable of 430HP after high flowing, and larger OP6 are capable of doing around 460HP.

PU high flow option is available for any one chasing for 450 to 500HP. They are built with a larger .82 internally gated turbine housing with Nissan OEM bolton pattern, braided oil feeding line and a high pressure actuator.

Below is the Rb25det Hitach turbo high flow catalog with few dyno sheets.


ATR43SS is a OEM replacement powered up turbocharger built for RB20/25DET R32, R33 and R34 GTST and Stegea models. They are T3x based with OEM dump pipe pattern. This series is specifically engineered for speed with smooth street driving ability.


ATR43 is a OEM replacement powered up turbocharger built for RB20/25DET R32, R33 and R34 GTST and Stegea models. They are T3x based comes in .63 and .82 turbine housing with OEM dump pipe pattern. Power is rated from 450HP to 600HP depends on profile chosen.

Initial release date: 24/08/2009:

We also carry out turbocharger repairs, housing/CHRA modifications and high flow services for All Garrett, HKS, Mitsubishi, Toyota, KKK and Made in China turbochargers. Do feel free to PM / contact us for free assistance. Check (if you live in usa): Costco Weekly Ad, or Supercheap Auto Catalogue.


Important Installation Notes for RB2xdet Highflowed and PU units:

Sleeve bearing turbochargers requires higher volume of oil flow, are sold with 50cm long braided oil feeding line line that replaces the standard oil restrictor in side factory oil lines, 12mm benjo bolt, and a M12x1.25mm speed flow adaptor. The adaptor goes onto the engine block, benjo bolts goes into the bearing housing with hollow screw supplied. 3x copper washers are required during installation, Which we can supply them for $9 additional or can be purchased at local auto stores.

Factory water lines: T3x bearing housing used are 3mms shorter then OEM Hitachi's bearing housings. Means water lines needs to be very slightly bent / forced backwards.

Stock actuator: We normally modify the factory actuator's fitting bracket allowing it for a bit of preloading. The actuator bracket bolt wholes has to be filed 5mms towards the turbine housing if not received with the turbo or getting fitted by others. Once done it can be adjust and pre-load ensuring the waste gate is 100% shut.

For PU high flowed and ATR43 units with larger Diameter turbine housings, the engine side water line needs to be slightly bent / altered around the housing area.

Installing ATR43 turbocharger:

ATR43 units generally runs on a round 3inches inlet and round 2 inches out let. It is highly recommended to run a metal intake pipe. How ever if you wish to bolton to stock gears you need: 1x 3inch straight hose, 1x 2.5inch metal sleeve, 1x 2inches 90 degrees hose, 1x 2inches metal sleeve. We can supply all those parts for $100 extra.

Tip for a easy installation would be removing the actuator with bracket pre-installation, that would allow lot more room for your tools to reach the manifold studs, and install the actuator and bracket back on after the rest of the installation is complete. Make sure the actuator is preloaded by roughly 3mms.

Since larger turbine housings are used, due to larger physical size most of them would be taller then stock pushing the exhaust back by roughly 15mms. Most cars would be running an aftermarket exhausts, depending on the angle of the pre-made dump / front pipe, check the clearance between that to the Air-con water drain pipe. If fouls, simply by pulling it back with zip ties and secure it on the chassis.

Easy Induction pipes:



Couple of extremely important factors:

1. After turbo installation do check pressure leaks ( I can make you a simple plug with a hose nipple for $50). Turbo will not perform if there are leaks.

2. Most of our turbos are installed with a 18psi high pressure actuator. by pass all boost controlling devices on test run, Boost gain from EBC based on stock actuator will cause massive boost creep.

3. Make sure the car's got a at least 3inch metal induction pipe with pod filter. Do not run those metal stuffed stock intake pipe.

4. An good exhaust system should restrict no more then 10KWs (My HKS silent power made 3KWs restrictions on a 316rwkws application). So Dyno tune with cat and exhaust dropped, (front pipe only). Do a touch up run with exhaust on after tuning, Get a better exhaust if you see a massive power drop with exhaust.

If above procedures are followed you will definitely get the desired power goal.

Also people with RB25det R33s. pay attention to those 20 years old valve springs and valves. Mine were all chewed out and worped possibly from valve float. That will act as boost leak, causing lose in power and response. Recommend stronger valve springs.

Order, dispatch and mechanic services:

All turbochargers are specifically built to suit customer's orders. We need in average 3 to 5 working days to have the order complete. We normally send with Australian post registered post with insurance, which generally takes 3 working days for delivery.

We have 2x clients workshops in Melbourne which can carry out the installation service for $200, or onsite service for $250.

For tuning, I personally use and recommend Status, and Dr.drift.



For R33 RB25det I've personally used Adaptronic Plugin ECU and highly recommend it. The RRP price on this mode is $1499, We offer $400 discount of total if it is purchased with any of our turbochargers or high flow / rebuild service. Discount also apply for any customers whom is currently owning one of our built or high flowed turbochargers. Please check ECU features, results and discussion in page 113~116.

Hi Stao,

Just thought I would add to this thread for all the people out there thinking of getting one of your highflows.

These are a great option for upgrading you turbo and the workmanship and support from Stoa is absolutely fabulous.

Although I have not yet had my Highflow(G3 Profile) tuned I can honestly say that the response is very similar to the stock turbo and you can feel the power increase across the bandwith.

Awesome Turbo mate.

Stao, on your dyno sheet above you cannot quite see the R33 results clearly, What kw's did you get on the readout with the PFC?? (14 & 17psi)

Here's the R33's hiflow result based on a small stock R33's rear turbine housing. It had a exhaust leak through the Turbo to manifold gasket and running a Bleed valve controller. Boost peaked to about 17psi and droped to 15psi.

This is a runin tune and a final tune.



and yes we can high flow GTR turbos to 300HP each using 360 degrees thrust bearing T28CHRA. or a Garrett GT2860Rs ball bearing CHRA depends on your bugget.

Ahhh, Its Geraus's 33. He has told me about the boost leak.

So do you think that 250rwkw is achievable with the G3?

I have almost identical mods to Geraus

Ahhh, Its Geraus's 33. He has told me about the boost leak.

So do you think that 250rwkw is achievable with the G3?

I have almost identical mods to Geraus

With R33 stock housing its very close to its limit, maybe another 5~10 kws once leak fixed.

With RB20 turbo's high flow I'm not too sure as I haven't had one dynoed yet. I guess its probably archive close to 230rwkws.

Wheel size wise this is using the a 71mm comp with 65mm turbine. With Garrett GT2871Rs its running the same size comp wheel but 53mm turbine.

i too can highly recommend stao and his highflow service. I have the g3 profile on my neo. Getting it tuned tommorow at status tuning so will be great to see what it can do.

Hey stao what rwkw do you think i should get maxing out the standard injectors? being an auto im hoping around 220rwkw...

now seeing this I'm torn between high flowing my Neo turbo and getting an TR43 G2, they both appear to acheive the same kw.

Stao, which would have better response between a high flowed Neo 450Hp and TR43 G2 on a RB25. As if i remember correctly there is roughly a $300 difference between the 2 for the configuration that i wanted.

also which 1 would have more head room for future upgrades.

Can you rebuild and/or high flow a CT20?, off a toyota 1JZ VVTI? (these are the 2.5L single turbo).

heheh thats my highflow and my graph !!!:P yeh guys i recommend this if you guys wana save money! these turbos are great, i dont even put my foot down till 3,500 i get 17.6psi . seriously it spools up so quick. Tao is a very good guy , very good dealer. recommeneded!!!!

oh and sorry tao your wrong i wasnt using a bleed, im using a Profec Spec - B II . The reason why its dropping boost is because my cooler pipes are leaking! =)

i would also like to thank Tao and Trent @ Status tunning :) ! =)

Stock injectors gets maxed around 230rwkws. Should see 220rwkws no problems.

The TR43G2 is some thing to get if you are targetting about 270rwkws. Its running off a .63 rear. It will be making more power then the high flow. Or you can go for the TR43i which is made to archeive 300rwkws if you have cams and injectors upgrade in mind.

For the CT20s we can also high flow them with ATR28G3 CHRA. which can produce about 260rwkws on a stock 1JZ.

The GTR high flows will be using the TR28KAI's CHRA. They produce about 550HP as a twin.

what supporting mods are needed for the G2 to hit 450whp? do you have any rb25 high flows setups that can get around 550whp on the stock exhaust manifold?

You are never going to find a hi-flow that will make 550rwhp/400rwkw... or 450rwhp for that matter... the exhaust housing is just too restrictive to flow anymore tan around 270rwkw (~360rwhp) fully machined. I think you need to do a bit more homework on turbos.

Yeh thats right r31nismoid, trent said my turbo housing was maxing out... hey dont forget i also have my injectors flowed at 740cc trent recommended them... Also my knocking is really weird... does anyone here know much about knocking?? on my PFC the knocking goes up and down...
